Title: Production of cross-linked aromatic polysulphones
Inventor: JONES MICHAEL EDWARD BENET
IPC: C08G75/20
Filed: 1964-03-18
Abstract: Cross-linked aromatic polysulphones are prepared by heating, preferably at a temperature of at least 220 DEG  C., a composition comprising a thermoplastic polysulphone containing aromatic residues (having one or more replaceable aromatically bound hydrogen atoms) and aromatically bound sulphone groups in the polymer chain, the polymer itself containing per chain at least two groups of the formula -SO2X, each attached directly to an aromatic carbon atom, or being mixed with an aromatic compound which contains at least two -SO2X groups each attached directly to an aromatic carbon atom, wherein X is a monovalent atom or group which promotes the thermal scission of an -SO2X group from an aromatic carbon atom.  The thermoplastic polymer is formed suitably of 100 to 70 mole per cent of -Ar-SO2-repeating units and 0 to 30 mole per cent of -Ar-CO- repeating units, where Ar is an aromatic residue derived from benzene, diphenyl or a compound of the formula <FORM:1107255/C3/1> wherein P is oxygen or sulphur.  In Examples (1) poly(diphenylether sulphone) is cross-linked with diphenylether - 4,41 - disulphonyl chloride and the melt allowed to foam as a consequence of the evolution of hydrogen chloride and sulphur dioxide; (2) a poly (diphenylether sulphone) is cross-linked with diphenylether-4,41-disulphonyl chloride in a solvent so as to form a film: (3) a polysulphone derived from diphenylether - 4,41 - disulphonyl chloride, diphenyl ether and 4,41-diphenoxybenzene is cross-linked with diphenylether - 4,41 - disulphonyl chloride: and (4) a prepolymer derived from diphenyl ether and excess diphenyl ether-4,41-disulphonyl chloride is self cross-linked by heating.ALSO:Asbestos paper is impregnated with a cross-linkable composition comprising a polysulphone derived from diphenylether 4,4\sv-disulphonylchloride, diphenylether and 4,4\sv-diphenoxybenzene, and diphenylether-4,4\svdisulphonyl chloride in nitrobenzene as solvent, the impregnated product dried and then pressed at 320 DEG C to cross-link the polysulphone and form hard rigid products.

Title: Improvements relating to railway signalling mechanism
IPC: B61L5/16
Filed: 1922-04-24
Abstract: 185,390. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Beall, C. R.). Sept. 2, 1921, [Convention date]. Visual outdoor signals.-The holding-magnets of electrically-operated semaphores are provided with two coils, energized from batteries of different voltages, in order to economize power consumption when the magnet has moved its armature. The holding magnet of apparatus of the three-position upper-quadrant type comprises a winding 16, Fig. 1, which lifts a pawl 13 against a ratchet-wheel 10 on the semaphore axle, and a winding 15 of thick wire, which merely retains the pawl in its operative position. A relay H, when energized, completes a circuit from a battery B, through the contacts 18, 20, 20<a>, motor 11, 12, and the winding 16, so that the pawl 13 is moved against the ratchet-wheel 10 and breaks a contact 47, thereby removing a shunt 45 from across the motor 11, 12, which moves the semaphore S. After 43‹ of movement of the semaphore, the contacts 20, 20<a> break the motor circuit, the semaphore continuing to the 45‹ or " caution " position by its momentum. The relay H also completes a circuit from a battery B<a> of low voltage, through the contacts 26, 29, 29<a> and the coil 15. This circuit remains closed when the " caution " position is reached, thus holding the semaphore in that position. The contacts 37, 37<a> make at 40‹ of movement, so that a relay D, when energized, completes a circuit from the bottom B, through the contacts 18, 35, and 37, 37a, motor 11, 12, and the coil 16, and the semaphore is moved towards the " proceed " position. The contacts 29, 29<a> break the holding circuit at 55‹ of movement, but the. circuit is transferred at 50‹ of movement to the contacts 41, 41<a>, 39, and 26. The contacts 37, 37<a> break the motor circuit at about 2‹ before the " clear " position is reached, and the semaphore completes its movement by momentum and is held bv the circuit through the contacts 41, 41a. If relay D be de-energized, the semaphore returns to about 2‹ past the " caution " position when the motor circuit is made through the contacts 20, 20a so that the semaphore is raised again to the " caution " position and is held by the holding coil 15. If both relays D and H be de-energized, the semaphore returns to the " danger " position, since both battery circuits are broken. In either case, the release of the pawl 13 shunts the motor 11, 12 by a resistance. 45, thereby breaking the fall of the semaphore. In a modification, a relay having neutral and polarized armatures controls the apparatus, and the resistance 45 is also controlled by contacts operated by the semaphore which make only between 35‹ and 45‹ of the movement of the semaphore. The movement of the semaphore is controlled by the direction of the current in the polarized relay. The coil 15 is short-circuited through a back contact on the relay armature, and is of the slow-release type, so that it does not release the pawl 13 during the reversal of the current in the relay.
